title: Fluid-path in the mandible and maxilla.
abstract: We examined fluid-paths in the maxilla and mandible of the dog, and compared them with Kihara's extravascular fluid-path-system. Areolar tissue is formed in the walls of the Volkmann's and Haversian canals. This tissue is composed of collagenous and reticular fibers. Kihara confirmed the collagenous fibers were encircled, however we could not ascertain whether they were encircled or not. We have compared the paths in the walls of the Volkmann's and Haversian canals with Kihara's fluid paths, and found the paths in the bone do not belong to the category of Kihara's paths. Namely, the term "extravascular fluid path" should not be applied to the areolar tissue in the bone. We suggest the term "fluid path" for this tissue in the bone. The areolar tissue in the walls of the Volkmann's and Haversian canals and endosteum communicate with one another. We call them collectively endosteum. Yoshikawa called the areolar tissue in the Volkmann's and Haversian canals perivasculäre lymsphräume. However, this designation is inadequate considering the actual characteristics of this tissue.
